Using internal ReAct sub-agents without MCP

I am testing out the sub-agents feature with my final year project on career counselling. Is there a way to use the internal ReAct sub-agents with a custom tool, without configuring an MCP? Initially i configured dummy values for the MCP in the sub-agents config.yml and endpoints.yml, but when i do rasa train, i get an error that rasa could not connect to that server. Pls help me out, it’s urgent. Thank you! :pleading_face: :folded_hands:

#Dummy values used (endpoints) :
mcp_servers:

  - name: dummy_server

    url: http://localhost:8080  

    type: http

# Dummy values used (/sub_agents/…/config.py):
connections:

  mcp_servers:

    - name: dummy_server
